Import Tips
• Provide CAS number (108-80-5) and spectroscopic data to distinguish from triazine salts or derivatives
• Ensure declaration specifies anhydrous form to avoid confusion with hydrated versions potentially seen as mixtures
• Label for pool stabilizer end-use carefully, as formulated products may require different classification
